Apache是​​否将PHP代码转换为某些形式？

Question

In some programming languages like C,C++,c#,Java,..etc when the code is compiled then the code is converted into another form in order to execute it. Does the Apache do the same or just it executes it without any conversion?

Answer 1

Apache doesn't do anything except handle the incoming request and serve the resulting output. Everything else is done by the PHP interpreter which pre-compiles the PHP code to a bytecode form, and then executes the bytecode instructions.
